Experimental study of two-dimensional elastic thin plate damage identification method based on modal curvature
Applied Mechanics and Materials(2012)
摘要
Two-dimensional elastic thin plates are widely used in civil engineering structures. The plates deteriorate gradually under service conditions, which influence the safety of engineering structures. How to identify the damage of the plate is one of the hot issues in the civil engineering fields. The relevant theoretical analysis and numerical simulation are stressed, but the physical model experiments are few. There are some problems among the theory, methods and practical engineering applications. A method is presented for determining damage location and degree of civil engineering structures based on model testing of two-dimensional steel plates.
